SPECIFICATION forming part of Letters Patent No. 252,585, dated January 17, 185.2.

Application filed June 15, 1881.

To all whom it may concern:

Be itknown that I, FRANZ NrTsoHMANN, a citizen of the United States, resident of Flatonia, in the county of Fayette and State of Texas, have invented a new and valuable Improvement in Flows; and I do hereby declare that the following is a full,elear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification,

and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal section of my invention. Fig. 2 is a bottom view, showing the manner of attaching the mold-board to the furrow-bar. Fig. 3 is a cross-section of the same; and Fig. 4 is a detail sectional view, showing how the handles are attached to the beam.

This invention has relation to plows; and it consists in the construction and novel arrangement of parts, as hereinafter shown and described.

In the accompanying drawings, the letter A designates the angular standardiron, the front or standard portion of which is curved upward, as shown in the drawings, and is threaded at its upper end, a, which'is designed to pass through a slot or bearing, Z), of the On the end a of this standard is the nut c, which is arranged above the beam and serves to limit the height of the beam with reference to the point of the plow and the mold-board. The front end of the standard forms the point B, and a horizontal extension or furrow-bar, 0, running back, is provided with an arm, D, at its rear end, projecting upward at an obtuse angle. This arm is perforated for the passage of the bolt (7, whereby the lower ends of the handles E E are secured thereto. At the height of the beam 1* in rear the handles are provided with a transverse bar, G, having shouldered and threaded ends 0 and securing-nuts g. Through a hearing or slot in the rear end of the beam extends the threaded end 7c of the hook-clamp H, which engages the transverse bar G, and holds it firmly against a plate or bearing, when the nut n is screwed on the threaded end k of said (No model.)

clamp above the beam. Between the handles and the standard portion K of the angular iron A is arranged the upright brace or post L, the upper end of which passes through a slot or bearing,p, of the beam, and the lower end of which is shouldered at q to engage a bearing, r, of the furrow bar 0, and is pivoted to said furrow-bar at 8 below said shoulder. The upper end of the brace L is threaded, as indicated at t, and it is provided with a nut, 1:, under the beam and supporting the same. It is apparent that by adjusting the nuts 0 and o the height of the beam can be regulated and the adjustment secured in a simple manner. So, also, the handles can be moved laterally on their transverse bar to give the plow side laud.

The mold-board N is a double-wing curved shovel having a notch, w, in front to engage a notch or undercut shoulder, z, of the point. It is secured to the standard by means of the curved plates or bearings P P, which are formed nith vertical downward flanges fat an acute angle with the bearing and designed to be applied to the sides of the standard, as shown, one on each side, and to be secured thereto by bolts m passing through the standard and flanges. The mold-board rests on and is bolted to the bearings P P, and also rests along its angular central line in front on the standard. In rear the ntoldboard is raised from the standard by means of an offset or lug, a, formed at the upper end of the moldboard in rear, as shown in the drawings.

Having described this invention, what I claim, and desire to secure by Letters Patent,

The combination, with the adjustable standard-iron A and the handles, of the transverse bar Gr, clamp or hook bolt H, and thepivoted adjustable brace L, connected to the furrowbar of said iron, substantially as specified.

In testimony that I claimthe above 1 have hereunto subscribed my nameiu the presence of two witnesses.

FRANZ NITSOHMANN.
